GTX320A - GTX327

[Special Delivery]

Anyone know if the GTX327 is tray/pin compatible with the 320A? My 320A needs repair and I have a 327 on the shelf. Thanks in advance for your help.

Garmin web page shows the 327 to be more than 1/2" longer than the 320, so I doubt they will use the same tray.

...which is a great source of information says this in their FAQ....

Yes, the GTX-327 utilizes the same mounting rack and mating connector as the GTX-320 and GTX-320A. The GTX-327 offers a few additional features but matches the standard connection pins as the GTX-320 and GTX-320A.

If you check the Installation Manuals for both transponders you can see that Garmin changed how they measure the depth behind the panel....

The two transponders have identical dimensions on the depth of their mounting trays, so the SE Aerospace FAQ does now make sense.

Thank you Mel and Gill!!!! I believed they were compatible, but I too noticed the measurement difference and then decided to pose the question to the VAF information Gods. I appreciate your research and prompt response... KEFD will send their thank you tomorrow.
